Description: "This bulletin tells how to grow sugar beets in the garden and describes a simple process of making from them a palatable and nutritious table sirup with a pleasant flavor. A patent for the process of making the sirup has been issued for the benefit of the public, so that anyone is free to use it. Tests have proved the process to be practicable. Sugar beets may be grown in any locality which has tillable soil that is capable of producing good crops of vegetables. A small piece of ground is sufficient for planting a few rows of beets -- enough to furnish the family with sirup. The tools needed are necessary in any garden operation -- a spade, a hoe, and a rake. All mature sugar beets, if properly handled, will produce a sirup. The beets are cleaned, peeled, cut into thin slices, and soaked in hot water to extract the sugar. The liquid is then treated and boiled down to the thickness desired. Detailed directions are given in the following pages." -- p. 2

Description: "A 'flat-headed,' milk-white borer, the larva or young of a small, slender, black beetle with bronze-red head and coppery red or golden thorax ('neck'), causes a reduction in the crops of raspberry, blackberry, and dewberry in the eastern half of the United States by its injury to the canes. The beetle, also, does some injury by feeding on the leaves of the plants. This insect may be controlled by cutting out the infested canes in the fall or winter, or in early spring before the beetles have emerged from them, and promptly burning the cuttings. Cooperation in the observance of this measure, including the same precautions on wild plants, for successive years, is highly desirable." -- p. ii
